About

This study investigates the effect of blood flow restriction with resistance exercise on functional mobility in pre-frail older adults. It is hypothesized that receiving resistance exercise with blood flow restriction will exhibit better improvement on functional mobility than only receiving resistance exercise in pre-frail older adults.

Full description

Participants aged over 65 years old with less than two items positive of Fried frailty phenotype assessment result will be recruited. The participants will be randomly assigned to two training groups, blood flow restriction resistance exercise and traditional resistance exercise. Both groups will receive the training 30 minutes/session, two sessions/week for six weeks. Muscle strength of the lower extremities and functional mobility tests will be used to assess outcomes at pre-training, 3-week after training, post-training, and one-month and two-month follow-up.

Ages: 65 to 95 years old

Volunteers: No Healthy Volunteers
